6lb pump blowing out carb?

Yeah but I would worry about a loose gas can. I did do this very thing before, but it wasn't for 25 miles. I'm going to get the new fuel line, it is only $60+ Ship. So I can do that soon enough and get it on the car. While I am waiting for the line, I can pull the tank, (Again) and check for debri. Would you happen to know anyone who sells brass floats for that year? 70 Duster? It has a leaky plastic one.

Are you going to run the Holley 650? Summit has brass floats for them.
